Ah ok, well but that’s a mod, it can be deactivated.
I mean, aoe2 have snowman MaA, some people like this stuff, others don’t, but it’s completely personalized so I don’t see a problem there.
It could be a regular unit, but until it’s not something that you just spam out of your foundries I’m fine if it’s something that you train in 1 or 2 units every 10 games.
Just hope the trash organ gun gets removed from Portugal.
The only trolling is Portugal with organ guns and spanish technologies.
Edit: It is indeed playable, but not buildable. Apparently you can only get one by advancing with the politicians of the imperial era.
Way to get the davinci tank:
Requires ‘Advanced Politicians’ card.
Then you advance with ‘The inventor’ in the imperial age.
I wonder if it would be possible to replace the War Wagon with another unit for Germans civ - Mounted Infantry (from Habsburg Royal House). In this way, a completely new Minor Civilization could be created that would specialize in sieges - Hussite Camp (visually it could resemble Karlštejn Castle surrounded by siege machines and Chapel).
Hussite Camp could offer training in War Wagons, Trebuchets and firearms precursors - Hákovnice (Unfortunately, it’s not in English).
Hákovnice (Unfortunately, it’s not in English).
Can be translated as “Arquebus” in English I think. The two words seem to have the same origin (hook gun).
